Alongside of the hook the shaft I, by properly turning which the 9o B we extend side plates or guides E, which ejector may be operated to lift its cross-bar h project forward to the front end of the hook, and force the link up off the hook. By prefoperate in a manner as bumpers, and relieve erence the ejector is keyed to the shaft by the hook of the'shock of the impact of two having its arm or arms provided with non- 45 meeting drawheads. A sufficient space c is circular openings and making the shaft non- 95 formed between the plates F. and hook B for circular to fit therein, so the turning of the the arms of the link, and such spaces c open shaft may effect the movement of the ejector, at the bottom of the draw-head and so permit while the shaft may be moved longitudinally a link held in one draw-head to hang vertiindependent of the ejector. Vhen the shaft 5o cally down and so be out of danger of being is made in tlichon-circular form shown, it is Ico preferred to provide the bearing-blocks J J, which have non-circular openings 7' in which the shaft is held and movable longitudinally, the said blocks .I being journaled in the drawhead, as shown. This shaft I is connected with the lock-bar, so its longitudinal movement may `eifect the movement of the said lock-bar to close the hook or clear the same, as may be desired. Now, this connection may be effected in various ways; but we prefer to accomplish it by means of chains K or the like-such as cords, ropes, or cogs-extended between the opposite ends of the shaft and the locking-bar, so that the movement of the shaft longitudinally may effect the adjustment of the bar F from locked to unlocked position, or vice versa.

In operation, to couple the cars the link' is held by the hook of one draw-head, the lockbar adjusted to locked position, and the link raised to vertical position, resting against face D, with its lower end in recess d. The other draw-head has its look-bar adjusted to unlocked position, and the two draw-heads are brought forcibly together, when the impact will jar the link down into engagement with the hook of the meeting draw-head, when the lock-bar of the latter may be adjusted to locked position and the coupling is completed. To uncouple, it isv only necessary to draw or push the shaft longitudinally to move bar F clear of the hook, when the shaft may be turned to cause the ejector to force the link olf the hook. It will be seen that the coupling and uhcoupling may be eected from either side of the car and without requiring any one to go between the cars.

Having thus described our invention, what we claim as new is- 1. ln a car-coupling, the combination of the link-securin g hook, the lock-bar movable into position to hold the link in engagement with the hook, and the shaft movable longitudinally and connected with the lock-bar, substantially as set forth.

2. In a car-coupling, the hook arranged for engagement by the link, combined with the lock-bar by which to hold the link in such engagement, the said lock-bar being movable laterally toward and from the hook and to both sides thereof, substantially as set forth. 3. In acar-coupling, the draw-head having a hook for engagement by the link and provided with a lock-bar by which to hold the link in such engagement, said bar being pivoted `in rear of the said hook and movable laterally at its forward end, whereby it may be adjusted over or laterally oft the hook, substantially as set forth.

4. In a car-coupling,the draw-head having a hook for engagement by the coupling-link, a looking bar or piece movably supported, whereby it may be adjusted to'hold the link in such engagement, and a spring engaging the lock-bar and operating by its tension to hold the said bar in locked position, substantially as set forth. l

5. In a car-coupling, the combination, substantially as described, of the hook adapted for engagement by the coupling-link, the lockbar pivoted'near its rear endhaving its forward end arranged and adapted for adjustment to close the hook, and provided in rear of its pivot with an extension, andthe spring arranged to engage such rear extension of the locking-bar, substantially as set forth.

G. The combination of the hook adapted for engagement bythe link, the lock-bar for holding the link in said engagement, the linkejector for throwing thelink out of such engagement, and the shaft connected with both such parts and adapted to operate the same, substantially as set forth.

7. In a car-coupling, the combination of the lock-bar, the link-ejector, the shaft keyed to said ejector, whereby it may be turned to operate or moved longitudinallyindependent thereof, and connections between the said shaft and the lock-bar, substantially as set forth.

S. In a car-coupling, the combination of the pivoted lock-bar, the link-ejector, the shaft keyed to said ejector and movable longitudinally, and chains orl the ylike connecting the opposite ends of the shaft with the lock-bar, whereby the longitudinal movement of the shaft may effect a movement of the lock-bar, substantially as set forth.

9. The combination, in a car-coupling, of the draw-head, the ejector having its arm or arms formed with non-circular openings, the bearing-blocks journaled in the draw-head and having non-circular openings, the shaft made non-circular in cross-section and fitted in the openings of the bearing-blocks and ejector, all substantially as set forth.

l0. The improvementinl car-cou plin gs herein described, consisting of the draw-head provided with a hook for engagement by the link, provided on opposite sides of said hook with side plates or guides, provided in rear of such hook with an upright face or shoulder and having at the base of such face or shoulder a socket or depression forming a seat for the end of the. link, the lock-bar pivoterl at its rear end and movable at its forward end over the hook, the link-ejector and the shaft keyed to the link-ejector and connected with the lock-bar, such shaft being movable longitudinally to operate the lock-bar and rotarily to operate the link-ejector, all substantially as and for the purposes set forth.
